Introduction

Read this manual carefully to ensure correct steps are done to attach the applicator to the baler. This

applicator is designed to apply Harvest Tec buffered acid. The model 491 base kit includes the following parts:

tank, frame, pump, gauge, hose, electronic control box, and miscellaneous hardware. The applicator can be

installed on most balers with the proper installation kit (not included.) Before installing the unit on the baler,

make sure you have the proper installation kit. (See the chart below.) If you are unsure about your installation

kit contact your local dealer for specifications. This applicator is crop eye compatible (Nov. 2003 and newer.)

For your convenience we have included a parts break down in the back of this manual.

Left and Right sides are determined by facing in the direction of forward travel.

Installation of Applicator

1. Installation of saddle, legs & mounting on baler

Hesston, New Idea, Challenger, and Case 8570, 8575, 8580, 8585, 8590 Balers:

3 X 3 balers only

Locate parts bag 2. Install both saddle legs (001-6707C) onto the saddle (001-6707A) with eight 3/8” x 1-1/4”

Bolts, locks and flat washers. The mounting slots in the legs will attach to the second and third weld nuts in

from each end, of the saddle, on both sides

1. Once legs and saddle are loosely attached measure the distance from the top outside corners of the

bale chamber where the saddle will be attached. Move legs in or out so the inside edges will match this

dimension. Also try to center the saddle within these dimensions. Do not fully tighten down bolts until

unit is mounted on the baler

2. Raise the assembly on to the baler and proceed on to the next page.

3 X 4 and 4 x 4 balers only

Locate parts bag 2. Install both saddle legs (001-6707C) onto the saddle (001-6707A) with eight 3/8 x 1-1/4”

Bolts, locks and flat washers. The mounting slots in the legs will attach to the first and second weld nuts in from

each end, of the saddle, on both sides.

Hesston, New Idea, Challenger, and Case 8570, 8575, 8580, 8585, 8590 Balers:

3 X 3 balers only

Mount the tank legs and saddle on the baler as shown above, centered between the compression arm and the

crossbeam. The tank legs bolt to the baler with six 1/2” x 1-3/4” carriage bolts, lock & flat washers and hex

nuts. Depending on the baler model, 9/16” holes (3 per side) may need to be drilled in the baler to bolt down

the tank legs. The bolts should be inserted from inside the baler. Tighten down the leg hardware, followed by

the tank and saddle hardware.

The saddle is intentionally tipped forward by 5o so that the tank cap will be parallel to the ground. There is a

small cut out “V” where the tank sump fits in the saddle and this cut out should face the back of the baler for

the tank to be level when installed on the baler.

4 X 4 balers with a removable ladder: Bolt the ladder bracket extensions (001-6707H) on the side of the tank

legs and attach the balers existing ladder.

The spray shield is installed on the gathering fork guard located in the back of the pick-up head. Existing bolts

are used to fasten the spray shield bracket to the gathering fork guards. Route hoses so they will not interfere

with moving parts. Rotating the flywheel by hand can check this. Don’t fasten hoses to metal hydraulic

lines! A parts breakdown is located in the back of the manual.

hole on the bottom lip of the baler. Use the clamp on the left hand side to tighten the shield against the

underside of the tongue. Tighten the clamp with the two bolts provided. A parts breakdown is located in the

back of the manual.

Installation Kit 4491

Install the spray shield behind the baler’s cross channel, which is located on the bottom side of the tongue

behind the flywheel. Note the position of the bevel on the spray shield. Clamp the spray shield around the

channel using the backing plates and the 1/4” x 7” bolts provided. A parts breakdown is located in the back of

the manual.

wrapper extensions so when tightened the bolts are in the top of the wrapper extension slot. Install the wind

guard stops 001-4436S as shown below. Two holes will need to be drilled per side. Mount using four 1/4” x 1”

bolts, locks and nuts. A parts breakdown is located in the back of the manual.
